Role of Induction and Adjuvant Therapy in Regionally Advanced / Resectable NSCLC Rodney J. Landreneau M.D. Professor of Surgery Department of CardioThoracic Surgery University of Pittsburgh Medical Center Pittsburgh, Pennsylvania
Stage IIIA Non Small Cell Lung Cancer A “heterogeneous” anatomic stage classification with difficult to interpret responses to therapy
Stage IIIa Non-Small Cell Lung Cancer Heterogeneity Microscopic mediastinal disease prognosis compared to macroscopic disease. Single station mediastinal node involvement compared to multiple station involvement Minimal clinical nodal involvement vs. Bulky mediastinal node involvement
Induction Chemo-radiotherapy for Stage III-a non-small cell lung cancer Standard of Care ???
